I worked on a Silverodo and the problem I was having was that 1 cylinder wouldn't fire.I changed the plugs the wires and replaced the air filter.I still got a misfire on my no. 5 cylinder.Tested the cam sensor and the crank sensor and they were fine.I finally took it to have a balance test done on the injectors and it was a bad injector.So I would get a balance test to see if you have a bad injector if you have done everything else.

Where can I get a manual for some model Daihatsu?


take no 1 plug out and watch the rockers for no 1 piston when the rockers are both on the back of the cam , ( valve clearance ) place a piece of wire in the plug hole to touch the top of the piston and as you carefully move the piston towards tdc the wire will move out until you get to a point where it starts to move back in
At the point where the wire moves out or in as you rock the crank at that point the TDC marks should be lining up
That is tdc no1 piston firing
also look at the other rockers and see which one is moving up (exhaust) and the other down (inlet) and that is the next piston to fire

THERE IS ONLY ONE FIRING ORDER FOR THIS IT HAS BEEN THE SAME SINCE 1960??? 18436572 WITH NO1 IF YOU ARE STANDING STRAIGHT IN FRONT OF THE ENGINE YOUR HEI DIST SHOULD HAVE 2 PRONGS STRAIGHT ACCROSS FACING YOU IF IT IS NOT YOU MUST PULL THE DIST, ROTATE THE ENGINE AROUND TO COMPRESSION STROKE, VERIFY THIS BY THE POINTER ON THE TIMING COVER SET IT TO 0 WITH THE PISTON IN NO1 CYLINDER UP IF NO 1 PISTON IS NOT UP FULLY EXTENDED IN THE SPARK PLUG HOLE YOU ARE NOT AT NO 1
IF THE PISTON IS FULLY EXTENDED AND YOU HEARD A AIR SOUND THEN YOU ARE RIGHT, PLACE THE DIST BACK IN TURN THE ROTOR 1 TO 2 NOTCHES BACK TO THE RIGHT AND HAVE SOME ONE CRANK THE ENGINE IN SPURTS, IT SHOULD DROP IN, THEN REPEAT THE PROCESS TO VERIFY YOU ARE ACTUALLY ON NO1 THEN BEGIN THE WIRING

How do i know my firing order is right first do i make sure my # one plug is up first


Yes. Bring number 1 piston to top dead center of the compression stroke. Remove the distributor cap and see which post on the cap the rotor button is pointing to. This is where the number 1 plug wire goes. Follow your firing order on the cap in the same direction the distributor turns and your firing order will be right.

I need the firing order for a 93 chevy blazer distributor.where is number 1?


Firing order for a 4.3 liter v6 1-6-5-4-3-2

#1 piston is the first spark plug drivers side front of engine.
Passenger side cylinders are 2 4 6
Drivers side cylinders are 1 3 5
Distributor rotates clockwise and the starting spot is marked with a 1 on the top of the distributor cap.
Make sure you note the position of the 1 on the old cap before you take it off so you don't rotate the new one 180 out

My 93 honda prelude dont start i did a full overhaul but i can get it to start timing is right so i dont know wat to do next


Timing is right, but the firing order is incorrect then it could not start. Make sure connection at the spark plug is in the firing order. Let get back to the basic: need spark and fuel. After several cranking, take plug # 1 out to see if it wet. If it is wet then you have fuel. If it is dry then you don't have fuel. Start to find out what is the root cause for fuel not coming. Now touch the spark plug to the engine chassis and have a helper to start engine. If there is spark strong then you have spark. If no spark then you know what to do: find the root cause of the problem. If you have spark and fuel then need to recheck timing by Top Dead Center: Piston #1 is up, mark at camshaft and 0 mark at crankshaft all line up together while intake and exhaust valve closed. Good luck.
